Size specifications of popular industrial wind turbines
Vestas and General Electric (GE) dominate the market for industrial wind turbines in the U.S. Many older U.S. facilities use NEG Micon turbines, and Vestas has absorbed that manufacturer. Other older facilities use turbines from Zond, which was acquired by Enron, which in turn GE acquired to get into the racket. Information about Vestas models can be found at https://www.vestas.com/, GE models at https://www.gepower.com/businesses/ge_wind_energy/en/index.htm, Siemens Bonus models athttps://www.powergeneration.siemens.com/en/windpower/products/, Suzlon models at www.suzlon.com./product_overview.htm, Clipper models at https://www.clipperwind.com/, REpower models at www.repower.de/index.php?id=12&L=1. Enercon, Führlander, Mitsubishi, and Nordex are also major manufacturers, but their turbines do not appear to be currently used in the U.S.

*This figure is actually half the rotor diameter. The blade itself may be about a meter shorter, because it is attached to a large hub.
†Where different hub (tower) heights are available, the usually used size is presented.
‡Rotor diameter (m) × π × rpm ÷ 26.82
§The rated, or nominal, wind speed is the speed at which the turbine produces power at its full capacity. For example the GE 1.5s does not generate 1.5 MW of power until the wind is blowing steadily at 27 mph or more. As the wind falls below that, power production falls exponentially.
